Snodgrass Urethroplasty in Application of Hypospadias Repair

Objective To summarize the proper indication and methods for the repair of hypospadias,evaluate therapeutic effect of Snodgrass urethroplasty. Methods Tubularized incised plate urethroplasty was performed in 78 cases of hypospadias including 18 coronal,54 corpus of penis,6 penoscorotal types.Their age was from 16 months to 18 years with a mean 4.5 years.14 children had a history of failed urethroplasty.52 cases complicated with chordees deformation,white tuonica was folded and shorten at 12 points of the penis dorsal lateral.Bladder drainage was maintain for 12～14 days,anterior urethral was dilated after withdrawing the drainage. Results The patients were followed up for 4 months～2 years and a good function neourethra with a vertical slit-like meatus was observed.There was no chordee or stricture.7 patients(9.0%) had urethral fistula,2 were self healing after urethral dilatation,4 were corrected with urinary fistula repair,one had been corrected with Snodgrass urethroplasty. Conclusions Tubularized incised plate urethroplasty can be used in distal and proximal hypospadias repair including those with no or mild chordee.It is especially indicated for patients without enough penile skin after failed urethroplasty.Excellent functional and cosmetic results with fewer complication can be gained by using Snodgrass operation.
